Abstract
Method of imprinting on a soap bar or soap sheet which includes steps of providing printed matter on the surface of the soap and isolating the surface from water contact, such that the printed matter is substantially water-insoluble to provide a cost effective soap bar or soap sheet having printed matter on a surface thereon. The surface is protected by a protective layer which is substantially water-insoluble. The protective layer can be a varnish layer printed on transfer paper and affixed to the soap as a label. The printing color is durable in water or other predetermined diluents and in water-soap solution.

- a. providing said soap bar or said soap sheet whilst said soap bar or said soap sheet is partially wet;
- b. providing an inkjet printer and inkjet ink therein;
- said inkjet ink is heated to a predetermined temperature as required for optimizing coating performance and for better adhesion of said inkjet ink to the surface of said soap bar or said soap sheet;
- c. ink-jetting said heated inkjet ink directly onto at least one surface of said soap bar or said soap sheet;
- wherein said inkjet ink is in direct physical contact with said surface;
- d. applying at least one water-immiscible printed matter protective layer onto said ink-jetted soap surface;
- thereby sealing said soap surface from water contact;
- wherein said ink is printed onto said soap bar or said soap sheet, while said soap bar or said soap sheet is partially wet, in said ink-jetting step before fully drying said soap bar or said soap sheet.
